Disto: Ubuntu Mate 16.04 LTS
GPU: R9 380
I did not have a problem until I installed AMDGPU Pro drivers. The set up worked with default AMD GPU and works on Windows.
Ran xrandr both monitors detected as DVI-D
Problem: Monitor 2 is vga connected via DVI-I adapter.
Troubleshooting:Hooked my 32" tv via HDMI and swapped my DVI-D monitor over the DVI-I port and they both worked.
I think the problem is for w/e reason my system is reading my DVI-I port as a DVI-D port. Therefore no analog data is being sent out.
After hours of googling and reaching out on other venues I have made no progress.
